First, most people who are raped in prison are smaller, weaker inmates. Many are in for drug charges and don't remotely deserve to be raped — tortured — in prison. Second, even for people who commit more heinous crimes, its society's job to punish them, not the inmates. Inmates aren't raping or beating up other inmates to serve justice. They are doing it because they are sick, sadistic animals who get off on hurting people.
If we want a severe penalty for people like this killer, fine. Let society impose one. But putting people in jail on the hope that they get raped or beat up is wrong.
I did comment on the reality that she will face in an adult prison for serious felons like her did not in any way indicate that I think that she or anyone at all deserve any abuse, much less "rape."
As to the heinous and despicable acts of some in prison, it is my believe that it is these people who actually deserve a death penalty for they merely continue to victimize society, in or out of prison. It is they that do not deserve to live with humanity, the guilty or the innocent.
It is my prayer that this girl, come to recognize her poverty of morality, come to understand that her victim's life was precious and that she stole that life, that she come to understand that she deserves to be punished for her deeds and that asking for any kind of clemency(which she will probably get at some later date), but that as she denied the right of her victim to live, she should pay with her own life and accept that fact. Anything less from her is an injustice to murder victims every where.
